Answer:
This problem is a rate times time problem. To find the total amount, you must take the rate per unit of time, and multiply it by the given unit of time
Step-by-step explanation:
-5degrees/hr x 6hr=-30 degrees
We know that
tan ∅=opposite side angle ∅/adjacent side angle ∅
adjacent side angle ∅=opposite side angle/tan ∅
in this problem
see the attached figure to better understand the problemangle ∅=80°
opposite side angle ∅=12 ft (AB)
adjacent side angle ∅=? (AC)
adjacent side angle ∅=12/tan 80°------> 2.12 ft
the answer is2.12 ft
Step-by-step explanation:
it is option c. you interchange the value with y and take inverse.
